Am I in trouble?

A man I have been dating for almost 7 months out of nowhere stopped returning my calls and texts. The other night I finally heard from him and He says he's terrified of relationships and that when everything is right he will just know and won't be so confused. Should I take that as he doesn't think I'm the right girl for him? Or should I stick with him and continue our off and on relationship? The problem I have is I know I want to be with him and he's my other half. How do I help him cope with everything or even help him figure out what he needs so I can move on if need be.
